Bridge products, what to look for.

For folks who want organic, but don't want to pay the full price, can anyone suggest quality components to look for in a bridged fertilizer? I want a product that has the most benifits, and breaks down as closely to organic as possible.
Are these elements ok, or will they be counter productive to my programs.
Methylene urea
Potassium sulfate
Mesa
Nitroform
Ammonium sulfate

Any thoughts on what type of products often added to Organics that would not be counterproductive to building healthy soil?

Thanks
Jay

If you don't want to pay full price for the organic fertilizers, find a good organic fertilizer (or three) and look at the ingredients. Then go to your local feed store and buy as many of the ingredients as you can find so you can mix your own. The cost for the ingredients is typically 1/4 to 1/10 the cost of the commercial organic products.

With organic products, all the ingredients are listed. With chemical fertilizers, say a 10-5-5, the percentage of fertilizer salts adds up to 20%. I've always wondered what the 80% of the bag was that was filler?
